i just threw a rod bearing in my blazer and i was thinking about building the next one up a little bit.....any ideas??

 

Are you asking about increasing performance with another engine? Heck, the list could go on forever...

1. Port/polish heads, exhaust, intake. Probably the cheapest route, with a lot of gain. Preferable to doing this before doing anything else on this list.

2. Cam

3. Pistons/connecting rods/crank

4. Eh, it's early in the A.M, I'm sure someone else will chime in with other suggestions.

 

Yah basically if you want to make it stronger and have more power you can basically change out all stock engine parts for aftermarkets. The whole key to the rebuild will be how much money do you have to do it. What makes you wanna rebuild one stronger with more power,did you wear out this engine quick?

 

i kinda wore it out quick but i want to build it......im puttin a crank kit on it to fix it and then a cam but what other things could i do???

 

Put a 3.75" crank in will give you a 4.6L or 282ci motor with the stock 4.00" bore, or a 4.7L with 4.030 bore. Combine that with a cam, ported heads, and the Mercruiser marine intake and good tune and you should have a potent lil V6.

 

Find a cylinder head repair shop that is established and ask their advice since you will want to start there first to have the heads rebuilt, maybe even planed since they will check for warping. Those guys generally have great knowledge of how far/hard you can push the limits on a rebuild - given your budget - and can steer you clear of some aftermarket manufacturers poor designs of their parts.

 

So building up the 4.3L....

Put a bigger crank... making it like a stroker motor? and then maybe bore it out a little to get a litt more displacement....

Re do the stock heads? Like have the ported an smoothed...?

New Cam? (heard that makes about 42 hp+)

New Pistons....

How much would that cost??
How much could I do?

 

Are you doing the work yourself? If you are then you can figure about $1500 to thousands. If your having it done, then about $3000 to rebuild back to stock. If the block isn't damaged.

 

Depending on the condition of the block, crank, pistons/rods, cam, lifters, pushrods, heads, and valves, a budget rebuild can be done for MUCH lower than $1500. The master rebuild kit (less pistons) is ~$250 and that will include all gaskets, seals, bearings, and rings.

 

You might consider a long block replacement. It would be a lot eisier and quicker. I purchased a GM Goodwrench remanufactored engine (Long Block) and installed it myself. I have over 60K on the replacement engine and it runs great. The nice thing about the GM Goodwrench Engine is the warranty. The engine is covered for 36 months or 100K and is valid at any GM dealership and it does not matter who installed the engine. (The key is to shop around for the best price as there was a wide range of price quotes for the same engine) A local chevy dealer gave me the best price and it made it convnient to return the core. I even went with a GM Goodwrench Transmisssion last year when mine tranny went out.
